Patch, including a new mochitest test case

I've added a mochitest test case in this patch. Otherwise, it is identical to the previous, which tries to incorporate feedback from Neil's last post. I've verified that this test case fails without the patch to nsHyperTextAccessible.cpp, and that it passes with the patch. I've added the new testcase to accessible/tests/mochitest/Makefile.in, and reran the a11y mochitests. Everything seems to be working.
